For a while, the jeep was bogging down, misfiring and had a really rough idle. Now it won't start at all.

Its turning over but wont fire. Pulled the plugs and I have a spark and fuel is definitely getting through.

Thought maybe crank position sensor, but would I have a spark if thing was out?

Thanks, Matt.

btw, 93' 2.5 4cyl 5 speed

Crisp blue spark or yellowish spark?

yellowish

Needs to be blue. Your coil may be taking a dive on you.

Last time you replaced cap, rotor, and wires?

Only owned this jeep for just over a year. I haven't replaced the above in that time. Suppose its a good place to start. Could grounds be a possibility?

I would at least replace the maintenance items.

See what brand name is on your coil. If it's Magnetti-Marelli, I think they were the bad ones.
